They spend a fair amount of time fitting the oxygen mask and instructing about the visor relative to the mask. The mask is supposed to be secure but comfortable and when it is the visor may not lock in place. Unfortunately I missed that in the instructions and when we took off and I discovered it would not lock down in place, I continually fiddled with it attempting to make it secure. This went on for a few minutes with me wondering what it would be like to bail out at 80,000 feet with it not secured. And then I wondered what my source of oxygen would be were that to happen. And then I decided these were all questions best not asked at this point as we began the accent. I never did get it locked and it was only after I got home and looked at the instruction part of the video that I realized what I was supposed to have done. Pay attention Bill.
